Air conditioner condenser

ABSTRACT

A condenser for connecting any standard auto air-conditioner to a water cooled one so as to cool the interior of a boat cabin; the condenser being operated by a motor and consisting of a sealed housing having a coiled copper tubing therewithin, the tubing ends extending out of the housing and one end of the tubing being connected to a compressor and the other end being connected to a receiver of the auto air-conditioner; and an inlet and outlet being connected to the housing interior so as to flow water through the housing, the inlet being connected to a water pump, while the outlet is connected to the boat bilge line.

1/ I II II 1 III III/III I I III/I I AIR CONDITIONER CONDENSER This invention relates generally to air-conditioning equipment.

A principle object of the present invention is to provide a condenser for connecting any standard auto airconditioner to a water cooled one so to cool the interior of a boat cabin.

Another object is to provide a condenser that can be quickly and easily installed.

Yet another object is to provide a condenser that does not require any expensive generator, nor a space for housing the same. 7

Yet another object is to provide a condenser that will effectively cool a boat interior of a boat during mid-day heat in hot tropical climates.

Other objects are to provide a condenser which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily apparent upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a perspective view of the invention,

FIG 2 is a cross section on line 22 of FIG. 1.

FIG. 3 is a fragmentary cross section of a modified design thereof.

Referring now to the drawing in detail, and more particularly to FIGS. 1 and 2 thereof at this time, the reference numeral represents an air-conditioner condenser according to the present invention wherein there is a sealed housing 11 which has an inlet pipe 12 at an upper corner thereof and an outlet pipe 13 at a lower corner thereof so to allow sea water to circulate through a central chamber 14 of the housing.

Within the chamber 14 there is a coiled copper tubing 15, the ends 16 and 17 of which extend outwardly of the chamber 14 at upper and opposite lower corners of the housing respectively.

The inlet pipe 12 is connected to a water pump for pumping sea water into the chamber; the outlet pipe being connected to the boat bilge line.

The tubing upper end 16 is connected to a compressor, while the lower end 17 is connected to the receiver of the auto air-conditioner. Freon is circulated through the tubing.

All of the equipment is made of material or lined with material that is resistant to salt corrosion. The housing can be made 16 by 16 by 3 inches in size. More than one unit can be installed depending upon the area intended to be cooled.

Brackets 18 and standard fitting 19 are used.

Reference is now made to FIG. 3 wherein the housing 20 includes the coil 21 and the water intake pipe 22 are spirally wound together for increased efficiency in cooling the tubing. Thus the coolest of the water directly from the sea is adjacent the tubing. Perforations 23 allow some of the sea water to escape from the sides of the inlet pipe along its entire length.

While various changes may be made in the detail construction, it is understood that such changes will be within the spirit and scope of the present invention.

I claim as follows:

l. A condenser for cooling a refrigerant with sea water, comprising an unitary water tight housing having an inlet and an outlet for the circulation of sea water therethrough, in combination with an inlet and outlet for the flow of refrigerant therethrough, including tubing interconnecting the refrigerant inlet and outlet, in combination with a conduit connected to the sea water inlet, said conduit and said tubing lbeing spirally wound together whereby an efficient transfer of heat from the refrigerant to the sea water is effected due to the proximity of the coils and the conduit wherein said conduit is perforated and terminates in the housing to cause the sea water to impinge more directly on the tubing.
